SPX Technologies (SPXC) Q4 2025 earnings review
Aggressive M&A and Capacity Expansion Fuel Double-Digit Growth
SPX Technologies delivered an exceptional quarter to cap off a strong 2025, with Q4 revenue growing 19.4% and Adjusted EPS surging 24.5%. Unlike many industrial peers struggling with volumes, SPX is facing a 'good' problem: demand in Engineered Air Movement and Data Center cooling exceeds their current production capacity. The company continues to successfully execute a highly acquisitive strategy, with acquisitions (KTS, Sigma & Omega) driving over half of Q4's revenue growth. FY26 guidance projects an accelerating, highly profitable trajectory, targeting ~20% Adjusted EBITDA growth. The only crack in the armor is a sharp deceleration in the Detection & Measurement segment's organic growth.
🐂 Bull Case
SPX consistently generates operating leverage. FY25 Adjusted EBITDA margins expanded 120 bps to 22.4%, and FY26 guidance implies further expansion to ~23.5% at the midpoint.
The successful launch of the Olympus Max cooling solution places SPX perfectly into the hyperscaler CapEx boom, transforming the HVAC segment's long-term addressable market.
🐻 Bear Case
While overall Q4 revenue looked stellar at +19.4%, organic growth was only 7.6%. D&M organic growth specifically decelerated to just 1.7%.
With KTS and Sigma & Omega in 2025, plus Thermolec and Crawford United announced for Q1 2026, the sheer velocity of acquisitions increases execution and integration risks.
⚖️ Verdict: 🟢
Bullish. Management is executing flawlessly on both M&A and margin expansion. The CapEx investments to relieve capacity constraints and the robust FY26 guidance signal high confidence in continued momentum.
Key Themes
M&A Strategy is the Primary Top-Line Engine
SPX is leaning heavily into strategic acquisitions to scale. In Q4, inorganic growth drove 10.9% of the total 19.4% revenue increase. The Detection & Measurement segment leaned entirely on the KTS acquisition to post a massive 26.3% overall growth rate. Management shows no signs of slowing down, recently announcing the Q1 2026 acquisitions of Thermolec and Crawford United's air handling segment.
Data Center Cooling and HVAC Capacity Expansion
Demand for Engineered Air Movement and cooling solutions continues to outpace supply. SPX has begun aggressively expanding capacity. This is evident in the Q4 CapEx spike to $68.5M (up from $9.8M in 24Q4). The launch of the Olympus Max product positions the company to capture surging data center construction spend, shifting the HVAC segment from steady replacement-driven growth to a secular secular growth story.
Detection & Measurement Organic Deceleration
A notable red flag contradicts the positive headline numbers: D&M organic revenue growth decelerated sharply to 1.7% in Q4, down from 26.5% in Q3. While the KTS acquisition propped up the segment's total growth to 26.3%, the base business appears to be facing project timing delays or softening end-market demand. Investors must monitor whether this is a one-quarter blip or a trend reversing.
Navigating Tariffs and Macro Uncertainties
Despite previously guiding that tariffs would create a net $0.08-$0.12 EPS headwind in FY25, the company successfully managed the impact through pricing adjustments and localized supply chains. However, with the macroeconomic environment remaining volatile, further reliance on pricing to offset potential new trade frictions could test customer elasticity in 2026.
Other KPIs
Accelerating dramatically. SPX spent only $23.6M in the first three quarters combined, before unleashing $68.5M in Q4 alone. This reflects direct execution of their stated strategy to build out new production facilities for TAMCO and Ingénia to meet robust HVAC demand.
Stable. Up slightly from $283.8M in FY24. The cash conversion remains solid despite the massive ramp in capital expenditures and inventory build-up ($302.2M, up from $271.0M) required to mitigate supply chain risks and support new product launches.
Guidance
Accelerating. The midpoint of $7.80 implies ~15% YoY growth, maintaining the strong double-digit momentum delivered in FY25 ($6.76). This indicates management's confidence in absorbing the recent acquisitions accretively.
Stable. The midpoint represents a ~13% YoY increase, slightly below the 14.2% growth achieved in FY25. This factors in the newly announced Q1 2026 acquisitions (Thermolec and Crawford United).
Accelerating. Up from the 24.5% margin achieved in FY25. This suggests that the ramp-up costs of new production facilities will be more than offset by volume leverage, higher pricing, and the margin-accretive profile of data center cooling products.
Accelerating. Up significantly from the 23.6% achieved in FY25. Management expects a more favorable project mix and full synergy realization from the KTS acquisition to drive profitability higher.
Key Questions
D&M Organic Growth Weakness
D&M organic growth dropped sharply to 1.7% in Q4. Was this purely due to the timing of project deliveries, or are you seeing a broader deceleration in the base run-rate business?
Integration Bandwidth
With KTS and Sigma & Omega integrated in 2025, and Thermolec and Crawford United closing in Q1 2026, how is management ensuring operational focus isn't stretched too thin across these varied platforms?
Olympus Max Conversion
You previously targeted $50M in 2025 bookings for the Olympus Max data center product for 2026 revenue. Are you tracking ahead of that goal, and what is the margin profile of those early wins?
